Method and system for triggering MTC device

1. A method for triggering a Machine Type Communication (MTC) device, comprising: sending, by a Machine Type Communication (MTC) server, a Bootstrapping Server Function (BSF) entity a request message that comprises information on a Generic Bootstrapping Architecture Push (GBA-PUSH) Information (GPI) request and information on a triggering request of triggering an MTC device, when the MTC device is not connected to the MTC server; generating, by the BSF through a GPI request processing flow, GPI, wherein the GPI comprises the following: a version of the GPI, random number (RAND) in Universal Mobile Telecommunications System (UMTS) Authentication and Key Agreement (AKA), Authentication token (AUTN) or AUTN(*), an identifier for Universal Integrated Circuit Card (UICC) application to use, an indicator for use of Mobile Equipment (ME)-based GBA (GBA_ME) or GBA with UICC-based enhancements (GBA_U), a concatenation of Network Application Function (NAF) Fully Qualified Domain Name (FQDN) and a reference point Ua security protocol Identifier (Id), a requested NAF-Key life time, a NAF Security Association (SA) identifier, and a message authentication code over the GPI; and adding, by the BSF, parametric information of a triggering instruction of triggering the MTC device in the GPI according to the information on the triggering request; and sending, by the BSF, the GPI that comprises the parametric information of the triggering instruction to the MTC server; wherein the parametric information of the triggering instruction comprises a Trigger Indication; sending, by the MTC server, the GPI that comprises the parametric information of the triggering instruction to the MTC device to be triggered; storing, by the MTC device, the GPI and subscriber-related information of the MTC device into a SA; and triggering the MTC device according to the Trigger Indication in the received GPI; the method further comprising: after the triggering the MTC device, returning, by the MTC device, a triggering response to the MTC server, and establishing, by the MTC device, a secure connection with the MTC server according to the SA.

2. The method according to claim 1 further comprising: before the sending, by an MTC server, a BSF a request message, registering the MTC device on the MTC server, and storing, by the MTC server, related information of the MTC device.

3. The method according to claim 1 , wherein the parametric information of the triggering instruction further comprises a Trigger Time during which the MTC device sends information after being triggered.

4. The method according to claim 1 , further comprising: after sending, by the BSF, the GPI that comprises the parametric information of the triggering instruction to the MTC server, storing, by the MTC server, subscriber-related information of the MTC device to be triggered and the GPI except the parametric information of the triggering instruction into a SA.

5. The method according to claim 4 , further comprising: before the sending, by an MTC server, a BSF a request message, registering the MTC device on the MTC server, and storing, by the MTC server, related information of the MTC device.

6. A system for triggering a Machine Type Communication (MTC) device, comprising: a Machine Type Communication (MTC) server, a Bootstrapping Server Function (BSF) entity and an MTC device, wherein the MTC server is configured to send the BSF a request message comprising information on a Generic Bootstrapping Architecture Push (GBA-PUSH) Information (GPI) request and information on a triggering request of triggering an MTC device, when the MTC device is not connected to the MTC server; wherein the BSF is configured to generate GPI through a GPI request processing flow, wherein the GPI comprises the following: a version of the GPI, random number (RAND) in Universal Mobile Telecommunications System (UMTS) Authentication and Key Agreement (AKA), Authentication token (AUTN) or AUTN(*), an identifier for Universal Integrated Circuit Card (UICC) application to use, an indicator for use of Mobile Equipment (ME)-based GBA (GBA_ME) or GBA with UICC-based enhancements (GBA_U), a concatenation of Network Application Function (NAF) Fully Qualified Domain Name (FQDN) and a reference point Ua security protocol Identifier (Id), a requested NAF-Key life time, a NAF Security Association (SA) identifier, and a message authentication code over the GPI; and add parametric information of a triggering instruction of triggering the MTC device in the GPI according to the information on the triggering request, and send the GPI comprising the parametric information of the triggering instruction to the MTC server; wherein the parametric information of the triggering instruction comprises a Trigger Indication; wherein the MTC server is configured to send the GPI comprising the parametric information of the triggering instruction to the MTC device to be triggered; wherein the MTC device is configured to, after receiving the GPI, store the GPI and subscriber-related information of the MTC device into a SA; wherein the MTC device is further configured to be triggered according to the Trigger Indication in the received GPI; and wherein the MTC device is further configured to, after being triggered, return a triggering response to the MTC server and establish a secure connection with the MTC server according to the SA.

7. The system according to claim 6 , wherein the MTC server is configured to, before sending the BSF the request message, accept registration of the MTC device and store related information of the MTC device.

8. The system according to claim 6 , wherein the parametric information of the triggering instruction further comprises a Trigger Time during which the MTC device sends information after being triggered.

9. The system according to claim 6 , wherein the MTC server is configured to, after receiving the GPI, store subscriber-related information of the MTC device to be triggered and the GPI except the parametric information of the triggering instruction into a SA.
